3.4.1. Virtual Server
This product’s NAT firewall filters out unrecognized packets to protect your Intranet, so
all hosts behind this product are invisible to the outside world. If you wish, you can
make some of them accessible by enabling the Virtual Server Mapping.
A virtual server is defined as a Service Port, and all requests to this port will be
redirected to the computer specified by the Server IP. Virtual Server can work with
Scheduling Rules, and give user more flexibility on Access control. For the details,
please refer to Scheduling Rule.
For example, if you have an FTP server (port 21) at 192.168.123.1, a Web server (port
80) at 192.168.123.2, and a VPN server at 192.168.123.6, then you need to specify
the following virtual server mapping table:
Service Port Server IP Enable
21 192.168.123.1 V
80 192.168.123.2 V
1723 192.168.123.6 V
Afterwards, click on “Save” to store your settings or click “Undo” to give up the
changes.
